The 'machine shown is of the general type in which by means oi' endless chains orthe like .trays or carriers holding the cans to be Fig. 9, is a plan view of a portion of one of the with it shaft 5 so long as the pawl S is in the notch 7. Vhen the pawl 8 is lifted out of engagement with notch 7, the gear will ro-` tate Without rotating the shaft 5 until the paw] is again permitted to drop into engagel nient with the notch. l On shaft 5 at opposite sides of the machine are secured a pair of eccentrics in `alinement, each connected by' an eccentric rod 2f with a bell crank lever 23, which is connected t by a link with a vertically movable cross soldeicdarc caused to travel from one end of the machine to the other successively over heating devices by which the solder is melted head 26 which is connected by 'vertical rods 27 with a pressureplate 46.I The bell crank levers 23, eccentric rods 24, links 25, cross heads 26 and yertical rods are inY pairs cori espending to the two eccentrics. LinksA connect the bell crank levers 23 with a second pair of bell crank levers 29 which are con nected by links 25 to a second pair of cross heads 26 which are connected by vertical rods 27 with a second' pressure plate 46.

Bell crank levers 29 are connected by links 30;` With a third pair of bell crank levers 31 which are connected by links 25 to a third pair of cross heads26 which are connectedV by vertical rods 27 with a third pressure plate 46 32 is a crank on the end of shaft 5 having vits crank pin connected to one end of a rack bar 33 having the rack at its free end in engagement with a pinion 34 which is loose on a shaft 35 mounted in the upper lportion of the frame of the machine. is provided with an annular flange 36 carrying a pawl 37 which is adapted to. engage a notch 38 in the inner periphery of a ring 39' which is fast on shaft 35. The shaft 35 is provided With a pair of sprocket Wheels 40, one at each side of the machine, each engaging one of a pair of endless chains 41'which pass respectively over one of a pair of idle Wheels 42 suitably supported at the end of themachine opposite that at which shaft 35 iS located. The chains are provided at suitable intervals with projectlons 43 for engagthe can bottom ,and can body preferably having at two diagonally opposlte corners eXtenslons adapted to receive the projecting tang or toe usual on the tops of sardine cans.

As the shaft rotates, pinionfB causes gear 4 to rotate which, the pawl 8 being in engagement with notch 7, causes shaft 5 to be rotated. As the shaft rotates carrying with it crank 32, the rack bar 33 operates the n pinion .A to rotate shalt 35 causing the chams el. to draw the hot llate 50 and und As t iechains cease tl rack bar 33 begins to "move in opposite directionv causing; the .pawl `37 to be disengaged from notch. 38, the eceentrics 22 ieir movement as the cause the pressure platee-6 to descend, the feet 48 to enter the can bodies Iand through to press the. can. bodies ydownward upon the can bottoms The plate being of such depth as to permit the-can bottoms to rest directly upon the hot plate 50,.the plate acts quickly upon thesolder to melt it. As thel eccentrics act to bring down the pressure plate, the cam 1.8 acts upon the lever 20 to ift the-pawl 8 .out of notch 7 and the shaft 5 thereupon stops unt-il the gearl has completed three revolutions when the cutaway cam 18 again comes opposite the enr-l of thelever 2O permittingr it to rise, releasing the paw] 8 which rengjages the notch land the shaft 5 begins again to rotate. The first effect of this 5 renewed through the he pressure plate and i 32 causes theshal't 35 to rotate. to draw the chains 41 forward advancingthe carrier with its cans quickly from hot plate 50 tohot pla-te and then as before described causes the pressure plate 46 to descend.. During the-interval between the raising of pressure plate 46 and the descent of pressure plate 46 the cans are relieved of pressure permitting the melted solder to distribute itself between the flange of the can body and the can bottom. After the tray or carrier has remained on the second hot, plate during` t'l'iree revolutions of the gears, thefshaft 5 is again operated as before to'cause the pressure plate 46 to be lifted and the carrier. advanced to cold plate 54 and to bring down. pressure plate 46. After gear 4 has again completed three revolutions, shaft is again operated raising pressure plate 46 andY carrying the tray or carrier with its now completely soldered can forward where it may be removed from the yiel dingl eccentrics, lifts t then through the cran tray or carrier forward over er pressure plate 46.v

i r l l l l i s and one tray or carrier 1s carried onto hot plate 50, a second tray or carrier is placed in position so that after the machine is once started one tray is on the cold plate and two others are under the first and second hot plates respectively during three revolutions of the gear 4.

The movement of the trays or carriers from one plate toanother takes place quickly and a relatively long period is allowed for the' cans to rest on the plates, the movement being' effected in one third. the time allowed for the resting of the cans ou the plate. The actual time taken either in the movement of the trays or in the heating or coolingl of the cans Of course as soon as very rapidly.

While the part soldered to the can body as above described has been termed the bottom serves assuch durinUr the filling ofthe can, it is in fact in the filledcan, the top being the part -Which is removed in opening the can.

I find that the tangs or toes 62 afford sufficient support for the can bottom and at the same time are not of sufficient area to prevent the melting of the solder throughout the full extent ofthe flange of the can' body. By providing grooves in the hot plates to receive these tangs or toes the can bottom is brought directly in Contact With the hot plate by which the solder is more quickly and evenly melted than Where a separate support for the cans is used or where the cans are heated by the direct action of flame.

While my bodied in a invention is herein shown em-' machine designed for soldering;` rectangular cans such as the ordinary sardine cans, it Will of course be understood that it maybe used in the solderingr of cans of any other formas Well.
